I found some steel slats down on the border. But I don’t see anything resembling a national emergency situation.. at least not in the McAllen TX area of the border where Trump will be today. pic.twitter.com/KRoLdszLUu

Sanders was one of several conservatives who highlighted Acosta's tweet to argue that a wall is an effective deterrent to illegal immigration.

Acosta responded a short time later, accusing Sanders of "twisting the truth again."

"As we have been reporting today there are other sections of the border that don’t have walls or slats," Acosta tweeted. "Yet, the residents here feel safe."

Acosta added that he was "glad she didn't doctor" his video, a swipe at Sanders for sharing altered footage of a November press conference that was used to justify the withdrawal of his press pass.

While I’m glad she didn’t doctor this video, unfortunately @PressSec is twisting the truth again. As we have been reporting today there are other sections of the border that don’t have walls or slats. Yet, the residents here feel safe. https://t.co/ueGbuldSBb
